Moon: Phases, eclipses, and tides
Moon � The moon does not give off light, rather it reflects the light of the sun. � The different shapes of the moon that you see from Earth are called phases. � The phase of the moon that you see depends on how much of the sunlit side of the moon faces Earth. � Phases of the moon � Waxing: the term used to describe a moon when the lit side is increasing. � Waning: the term used to describe a moon when the lit side is decreasing. � Crescent: less than half of the lit side is visible. � Gibbous: more than half of the lit side is visible.
Eclipses Solar eclipse: Occurs when the moon passes directly between Earth and the sun, blocking sunlight from reaching Earth. A new moon blocks your view of the sun. Diagram:
Eclipses Lunar eclipse: Occurs when the Earth blocks sunlight from reaching the moon. Only occurs when there is a full moon. Diagram:
Tides �The rise and fall of ocean water that occurs about every 12 hrs. �Tides are caused by the moon’s gravity pulling on different parts of the Earth. �Most places on the Earth experience two high tides and two low tides each day.
Types of tides �Spring tide: the greatest of the tides that occurs when the sun and moon are in line and gravity from both pull in the same direction. �Diagram:
Types of tides �Neap tide: the smallest of the tides that occurs when the sun and moon pull at a right angle. �Diagram:
